Hey Raytor, welcome to the forum!
One of my R9's will shoot anything, but I do not remember if I tried the Win. Ranger SXT ?.
But both of mine do shoot the Rem. 147 Golden Sabres fine.
It seems each R9 likes a particular round, but most do well with the Gold Dots.
Good Luck and have fun, hope you get to the range soon.
Let us know how it goes.
